IPhone 4 cannot access wifi from airport

Both my girlfriend and I have iPhone 4's. We cannot access wifi from my personal home airport. When we go to log into wifi and we type in the password, we receive a prompt saying, "Incorrect password for....". I am writing this on my MacBook, logged into my wifi, with the same exact password???????
I've tried everything. Resetting iPhone, MacBook, and Airport. I also tried resetting my password and resetting the network settings. I don't know what else I could possibly do. It's frustrating because my girlfriend is on a data plan and can't utilize our wifi.
Any ideas???????

Cannot access wifi since upgrading to ios5.1

I upgraded to IOS5.1 this morning. iphone 4S was fine, but ipad wifi did not reappear on completing the upgrade and when I enter my password, it says cannot access network. None of the details of the network are listed except for the DNS and I can't manually enter them. Anyone have any ideas or similar problems?

I'm seeing the same problem. Running iOS 5.0.1 both my original iPad and my iPad 2 were rock-solid on my WiFi network. Since upgrading to 5.1 neither device is able to connect for more than a few minutes. Device connects on a reboot or when resetting the WiFi settings but after a minute or two the network just disappears and the iPad says it's unable to connect. My iPhone 4 and 4S both work fine on the network with 5.1. This issue appears restricted to iPads.
Is Apple aware of this issue?

During configuration I cannot access available wifi to continue

Then connect to your computer via USB and setup the iPad that way.
Do other devices successfully connec to the network?
Try powring off and then back on your router.

HT4623 Cannot enable wifi or Bluetooth on an iPhone 5

I have a iPhone 5c and both the wifi and Bluetooth will not enable. The slider buttons stay grey in the off position. The phone was issued to me with OS 7.0.1. It was recommended that I upgrade the software to 7.0.3. Unfortunately without wifi that is not possible . I tried installing via iTunes but the install crashes.

Hi Roadrunner558,
Thanks for using Apple Support Communities. This article has steps to try if Wi-Fi is grayed out and unable to be turned on:
iOS: Wi-Fi settings grayed out or dim

With regards to the issues updating via iTunes and if the above does not work, I would recommend following this article to get the iPhone restored and updated:

HT4623 Since installing latest software I cannot access wifi,it seems there's a common term for this called greyed out.this is a software update issue as it's only happened since updating to latest IOS.Will there be a solution or is this the time to give

Since updating to latest IOS I cannot switch on wifi,looking at other sites it appears it's a software issue.how long do we wait for a bug fix as the common term greyed out is affecting a lot of phones after researching I phone users with the same issues.i know at the moment it's either move on to another phone system or do I risk the wait for a bug fix? I would like all with similar issues to list here so something might be done to resolve the software problem.

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

HT5934 IPad 2 cannot access wifi, even with the correct password.

My iPad 2 does not accept the password it should when trying to access the wifi access available at my employer. Once my employer removed his password protection from his wifi router, my iPad accepted the wifi. An iPhone accepted the same password today... It hesitated a bit longer than we expected, however, it did access the wifi router. We've tried multiple times, my employer uses Macs, and he's tried accessing his wifi with my iPad... He's even changed the name on his wifi, checked all settings, crosschecked that the password is a valid password, still, my iPad gives me an error "incorrect password ". It only makes sense if we were using an incorrect password, but we weren't! Help!

Is there any hope for an iPhone 4s that cannot access WiFi after iOS 8.1 ?

I bought a "very good" used unlocked 4s on eBay back on Oct 2 ... it arrived with iOS 8 installed ... AT&T folks told me not to load that SW when I went in to move my SIM from an Android phone to the iPhone ... when the saw it was already loaded they were amazed that it would even start up ... but it seemed fine until I got home and tried to set-up my WiFi ... all kinds of problems ... which led to upgrade to 8.01 and then to 8.02 ... all the while hoping to see some fixes ... but things went from not so good to terribly bad ... Bluetooth was off .. and the option to start it was greyed out ( but the little rotating gear continues to run constantly - can't stop that ) ... similarly the WiFi option was off and and was likewise greyed out and inaccessible ... then messaging was no longer accessible ... and to top it all off the phone now discharges in 2-3 hours ... even when powered off ... kind of scary ... but on Mon the 20th I was able to download iOS 8.1 to my Windows XP iTunes (took almost 6 GB to do that - downloads a huge file and then has to extract it, before installing it -- and instead of getting rid of the mess it makes, it puts the no longer needed files in the recycle bin taking up more space -- took me 6 hours to get thru all of that .... and all for naught ... still nothing works ... tried resetting networking ... resetting everything ... useless ... even drove 10 miles to a Starbucks to get a different WiFi ... but nothing works.

You should try these steps:
iOS: Wi-Fi settings grayed out or dim
Symptoms
In rare instances, the setting to turn on Wi-Fi on your iPhone, iPad, or iPod touch may appear grayed out or dim. You might see the following when you tap Settings > Wi-Fi.
If this occurs, your device won't respond when you try to turn Wi-Fi on. If you're using iOS 7.1, "Wi-Fi Not Available" might appear in Control Center.
Resolution
Follow these steps to resolve the issue:
Restart your iOS device.
Make sure that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
If you still can't turn Wi-Fi on, please contact Apple for support and service options. If you can turn Wi-Fi on but are experiencing other issues with Wi-Fi, see how to resolve those Wi-Fi issues.

IPHONE 4S CANNOT ACCESS WIFI

Cannot connect to wifi grayed

My iphone 4s is also completely useless when it comes to connecting to wifi. It won't even detect connection spots.   I do not know what happened but other people with other apple products do not seem to have a problem.
Depending on location it occasionally catches it, however it has been down for WEEKS now.   I purchased my phone from the apple store in January.   It should not be acting like this regularly.
I tried resetting the network settings.   Nothing works.
I am afraid to reset it to factor settings because I feel this is an internal problem with the phone, not the software itself.
I am not in North America right now, so the only thing I can do is be inconvenienced and wait. Unless there are other suggestions?

Ipad cannot access wifi

Can someone please help me. My ipad stopped accessing my home wifi yesterday. I've tried restore network, restore, restore, ad nauseum. I've tried downloading the new software and then restore and restore and restore again (both networks, and then all)
Please help.

My iPhone frequently cannot access wifi

Recently my iPhone 4S has become quite random when it's accessing the net via wifi. About 80% of the time it thinks there is no network and 20% it's fine. I access the same wifi networks that I have been using before. When this happens I can get access to mails etc by disabling the wifi and connecting via 3G. However this in not a very practical solution. Has anybody got any ideas? I have re-set the phone but the prolem persists.

The basics from the manual are reset, restart, and restore.
Have you tried any of these?
